Using Cisco CallManager Upgrade Assistant Utility 3.3(4)

The Cisco CallManager Upgrade Assistant Utility, a nonintrusive tool, detects the health of the servers in the Cisco CallManager cluster before you perform an upgrade to Cisco CallManager 3.3(4).

You obtain the Cisco CallManager Upgrade Assistant Utility from the web.

Caution This version-specific utility identifies problems that could cause the Cisco CallManager upgrade to fail. This utility does not correct the problem(s); you must perform the corrective action for the problem that the utility identifies.

Cisco strongly recommends that all servers in the cluster pass the validation before you upgrade any servers to Cisco CallManager 3.3(4).

Before You Begin

Before you run the utility, Cisco strongly recommends that you perform the following tasks:

•If you are upgrading from Cisco CallManager 3.1 or 3.2, upgrade the Cisco IP Telephony Applications Backup Utility to version 3.5.53 (or later). If you are upgrading from Cisco CallManager 3.3(3), upgrade the Cisco IP Telephony Backup and Restore System to version 4.0(2) or later. To obtain the backup utility documentation, see Table 1.

•Verify that your server login account has Administrative privileges to run the utility.

Understanding How the Utility Works

Before you perform an upgrade to Cisco CallManager 3.3(4), run the Cisco CallManager Upgrade Assistant Utility, a nonintrusive tool that detects the health of the servers in the Cisco CallManager cluster without changing the state of the system.

The Cisco CallManager Upgrade Assistant Utility version corresponds to the Cisco CallManager version to which you plan to upgrade the server. Use Cisco CallManager Upgrade Assistant Utility, Version 3.3(4), if you plan to upgrade to Cisco CallManager 3.3(4) from a compatible release of Cisco CallManager 3.1, 3.2, or 3.3. The utility will not run if the server is not at the minimum requirement for the Cisco CallManager 3.3(4) upgrade. Refer to the Cisco CallManager Compatibility Matrix for minimum compatibility requirements. To obtain the most recent version of this document, see Table 1.

Caution Your server login account must have Administrative privileges to run the utility. You may log in to the server by using the Administrator username and password.

Before you begin the upgrade on the publisher database server, you must run the utility on all servers in the cluster. If any server fails the validation process, investigate and correct the problem(s) before you begin the upgrade on the publisher database server. After you correct the problem(s), run the utility again before you upgrade.

You can run the utility on only one server at a time.

Cisco strongly recommends that you run this utility during a scheduled maintenance window.

If you want to install a later version of the utility, you must uninstall the version that exists on the server before you install the later version.

The utility runs the validation modules that display in Table 2. The utility runs some validation modules only on publisher servers, some validation modules only on subscriber servers, and some modules on both publisher and subscriber servers. As soon as the utility identifies a problem with a module, the utility begins checking the next module. After the utility performs the entire validation process, review the validation list in the Summary window for modules that fail the validation or for modules that provide warnings.

Additional Information

For Cisco CallManager 3.1 and 3.2

Backup File Integrity Validation

The utility performs this check if the server runs Cisco CallManager 3.1 or 3.2.

This check occurs on the publisher database server only.

The Upgrade Assistant verifies the following items:

•The existence of the chosen MCS.sti file

If the file does not exist after you click Select, an error message displays.

•The backup file size

•The backup utility version that is used to create the file

If you do not want the utility to validate the backup file, click the Skip button; a dialog box prompts you to skip the backup file validation.

If you do not choose a backup file for the utility to validate, the utility assigns a Skipped status to the module.

OS Flag Files Validation

The utility performs this check if the server runs Cisco CallManager 3.1 or 3.2.

This check occurs on the publisher database and subscriber servers.

The utility verifies that the Stirnw.flg and Stisys.inf files exist.

Database Location Setting Validation

The utility performs this check if the server runs Cisco CallManager 3.1 or 3.2.

This check occurs on the publisher database and subscriber servers.

The utility performs a check of your Cisco CallManager registry (specifically, dbconnection0) to verify that the registry points to the proper database.

For Cisco CallManager 3.3

Software Version Validation

The utility performs this check if the server runs Cisco CallManager 3.3.

This check occurs on the publisher database and subscriber servers.

The utility validates the Cisco-provided operating system/related service releases and SQL Server/related service releases.

For information on minimum software requirements, refer to the Cisco CallManager Compatibility Matrix. To obtain the most recent version of this document, see Table 1.

The Upgrade Assistant Utility checks only for software applications that this document lists. If you run other applications in the cluster or other applications on the servers, verify that compatibility exists between Cisco CallManager and the application before you upgrade. Failing to do so may cause applications to not work as expected.

Database Location Setting Validation

The utility performs this check if the server runs Cisco CallManager 3.3.

This check occurs on the publisher database and subscriber servers.

The utility performs a check of your Cisco CallManager registry (specifically, dbconnection0) to verify that the registry points to the proper database.

DC Directory HealthCheck Validation

The utility performs this check if the server runs Cisco CallManager 3.3.

Verify that the local system accounts for all Administrator accounts are set to Never Expire.

Note The utility validates the settings of the publisher database server even when it is running on the subscriber server.

Cisco CallManager Database Replication Validation

The utility performs this check if the server runs Cisco CallManager 3.3.

This check occurs on the publisher database server.

The publisher database server upgrade requires that all call-processing processes that the server handles fail over to the configured subscriber servers. Database replication must exist prior to the upgrade, so failover occurs.

This utility verifies the database replication status for all subscriber servers in the cluster. This utility validates that the database contains the latest information about the system. Validation results include Running, Idle, Failed, or Succeeded.

Hostname Resolution Validation

This utility performs this check if the server runs Cisco CallManager 3.3.

This check occurs on the subscriber database server only.

The utility validates that the server hostname resolves to a valid IP address.

Password Validation

The utility performs this check if the server runs Cisco CallManager 3.3.

This check occurs on the subscriber servers only.

The utility performs a check on each subscriber server to verify that the Administrator password on the subscriber servers matches the Administrator password on the publisher database server.

Installing the Utility

Caution If you choose to do so, you can use Virtual Network Computing (VNC) to install and run this utility. To obtain the most recent version of this installation document, see Table 1.

Do not use Integrated Lights Out (ILO) or Terminal Services to install or run this utility; Cisco installs Terminal Services, so Cisco Technical Assistance Center (TAC) can perform remote management and configuration tasks.

Step 3 If you are running the utility on a Cisco CallManager 3.2 publisher database server, continue with this step. If you are running the utility on the subscriber or are running a different version of Cisco CallManager, go to Step 5.

The Upgrade Assistant validates the Cisco CallManager MCS.sti backup file. Perform one of the following tasks, depending on whether the backup file is stored to a network directory, local drive, or tape device:

•Browse to the latest backup file that you have stored in your chosen backup destination.

•Specify the tape device that contains the tape backup. Use the format TapeN, where N specifies the tape device number (for example, Tape0, Tape1, and so on).

Tip If you do not want the utility to validate the backup file, click the Cancel button; a dialog box prompts you to skip the backup file validation.

If you do not choose a backup file for the utility to validate, this portion of the validation process fails.

Step 4 Click Select.

If the file does not exist after you click Select, an error message displays.

Step 5 The Upgrade Assistant Status window displays with a list of checks that the utility performs.

If you chose a backup file in Step 3, the Upgrade Assistant Confirmation window also displays the backup file name that you entered. Verify that you chose the correct backup file.

Step 6 Click Next.

An "x" indicates that the validation failed; a check indicates that the validation succeeded; "Skipped" indicates a validation task that the utility did not perform; an arrow indicates the validation task that the utility currently performs.

Caution Clicking Finish closes the window. Review the results before you click Finish. If you close the window, you can obtain the results from the log file; see the "Obtaining the Log File" section.

Note If a dialog box asks you whether you want to reboot your system, click No.

Step 8 After you fix the problems that the utility identifies, run the utility again on every server in the cluster before you begin the upgrade.

Interpreting the Results

The validation results display in the Upgrade Assistant Summary window. At the top of the window, a report summarizes the results for all modules and displays which modules failed, which modules produced warnings, which modules were skipped, and which modules passed. A link to the folder that contains all log files, including the Upgrade Assistant Summary report, displays also.

To identify a problem with the failed validation module, review the following information that displays in the Summary window:

•The first link points to the log file that specifies the error or warning.

Click the first link and search for the error or warning; for example, ERR: <message> or WARN: <message>.

•The second link points to the corrective action file that describes the log file error message and recommends the corrective action.

Click the second link to open the corrective action file. Search the corrective action file for the error message that is noted in the log file. Review the description and corrective action.

Caution After you correct all problems that the utility identifies, Cisco strongly recommends that you run the utility again on every server in the cluster before you begin the upgrade.

Obtaining the Log File

You can obtain the results from the utility in the following directory:

Tip In the Summary window, a link to the log file displays for every failed validation module. To access the log file, click the link in the Summary window.

The Summary.html file, which is the Upgrade Assistant Summary report, provides the exact same information that displays in the Upgrade Assistant Summary window.

Each time that you run the utility, the utility creates a new log folder and new set of log files. The utility does not remove the log files, even if you uninstall the utility. You erase the log files when you reimage the server or manually delete the files.
